Benefits of technology

The patent describes a method for making a color adjusting composition by mixing powder, colorant, and additive. This composition is then used to create fabric with good thermal insulation properties by weaving infrared reflecting fibers. The resulting fabric has low luminance and high infrared reflectivity, which is useful for protecting against overheating.

Problems solved by technology

In addition, since dark-colored fabrics are current fashion trends, how to effectively improve the thermal insulation of the fabrics, especially the thermal insulation of the dark-colored fabrics, has currently become a rather important issue.

s, Maximum Infrared Reflectivity, and Surface Temperature Change Tests for Fabrics

[0057]In this experiment, the fibers of the aforementioned comparative examples and embodiments are respectively fabricated into fabrics for the L*a*b* values, maximum infrared reflectivity, and surface temperature change tests. In the surface temperature change test, the condition is to use a halogen lamp with a power of 500 W and a wavelength of 750 nm to irradiate the fabrics for 10 minutes from a vertical distance of 100 cm. The testing results are shown in Table 3.

ness, Perspiration Fastness, and Light Fastness Tests for Fabrics

[0063]In this experiment, the fibers of embodiments 2, 6, 8, and 9 are respectively fabricated into fabrics for the washing fastness, perspiration fastness, and light fastness tests, in which the method of the washing fastness test is AATCC 61-2010 2A, the method of the perspiration fastness test is AATCC 15, and the method of the light fastness test is AATCC 16.2. According to the results, the fabrics fabricated by using the aforementioned embodiments can reach the grades 4 to 5 for the washing fastness and perspiration fastness tests to wool, acrylic, tedron, nylon, cotton, and acetic acid, and the fabrics fabricated by using the aforementioned embodiments can reach the grade 4 or above for the light fastness test. Accordingly, the fabrics fabricated by using the aforementioned embodiments have hardly any color transfer to wool, acrylic, tedron, nylon, cotton, and acetic acid, and can maintain their original color af...

Abstract

An infrared reflecting fiber includes 76.0 parts by weight to 88.5 parts by weight of a carrier, 1.8 parts by weight to 4.0 parts by weight of an infrared reflecting composition, 2.5 parts by weight to 7.5 parts by weight of a titanium dioxide containing composition, and 6.0 parts by weight to 16.0 parts by weight of a color adjusting composition. The carrier includes polyethylene terephthalate (PET). When a content of 5.0 wt % to 7.5 wt % of the infrared reflecting composition and a balance of the carrier are mixed together to form a first fiber, a maximum infrared reflectivity of the first fiber is between 61% and 70%.

Description

RELATED APPLICATION[0001]This application claims priority to Taiwan Application Serial Number 109114223, filed Apr. 28, 2020, which is herein incorporated by reference.BACKGROUNDField of Invention[0002]The present disclosure relates to a textile material and a method of fabricating the same, and particularly relates to an infrared reflecting fiber and a method of fabricating the same.Description of Related Art[0003]Under a trend of globalization, textile industry faces strong pressure due to competition. Textile traders must constantly develop new technologies and diversified products in order to face global competition.[0004]In recent years, due to greenhouse effect and global warming, the average air temperature has continued to rise. Facing the increasingly hot climate, various shading fabrics focus more on light blocking and heat reflection in order to enhance its thermal insulation effect and achieve protection. In addition, since dark-colored fabrics are current fashion trends...
